peugeot boxer 2.8 hdi none starter when cold

[alfredvicy]

Hi everyone
I have a peugeot boxer 2.8 hdi model 2009 van in on a 53 plate, Its a none starter in the morning unless you give it some sniff then it starts up and runs fine and will start every time until you leave it overnight. I've changed fuel filter and change the fuel pressure sensor located on the Common Rail, and also I check fuel injector in specialist Center for Diesel , but no positive result Up to this moment.

Thanks for the advice

Regards VICTOR

Hi!
What you have fuel pressure at the time of the morning start?

[alfredvicy]

in live data of Peugeot planet in the morning without start the engine only open the switch the rail presser sensor is (12 bar) , after try starting it come up to (950 bar)

disconnect the air sensor and the coolant sensor to check for improovements while cold

i disconnect the air & coolant sensors but nothing new, the same problem

[Albanais]

Then you have a problem with the glow plugs

[alfredvicy]

i change it also with a new one and i check the positive wear its working correct in the first start

[alfredvicy]

i forget to say thanks for your help ...

Any body have an idea what can I do

Then you might have a problem with the low pressure circuit. Buy a non return valve and put it on the return line and check for improvements. It happened to me many times that the fuel goes back so once you start it once it does not fail any more until you wait a couple of hours. So it is a cheap test to be done. Try it

i will try and report you
